    • To provide an image decoding apparatus that suppresses overhead of parallel processing to improve parallelization efficiency and reduce circuit costs, while solving neighboring macroblock dependencies. The image decoding apparatus (100) includes first and second decoding circuits (101, 102) having a transfer unit that transfers right neighborhood information or left neighborhood information, and first and second transfer completion detection units (104, 105) that respectively detect whether or not the left neighborhood information or the right neighborhood information has been transferred to the first and second decoding circuits (101, 102). Each of the first and second decoding circuits (101, 102) decodes a decoding target macroblock positioned at an edge of a region, when the transfer of the left neighborhood information or the right neighborhood information is detected. A boundary line between regions is orthogonal to a decoding direction corresponding to an order in which macroblocks adjacent to each other are sequentially decoded.
    • 提供抑制并行处理的开销以提高并行化效率并降低电路成本的图像解码装置,同时解决相邻的宏块依赖性。 图像解码装置(100)包括具有传送右邻域信息或左邻域信息的传送单元的第一和第二解码电路(101,102),以及第一和第二传送完成检测单元(104,105),其分别检测是否 不是左邻域信息或右邻域信息已被传送到第一和第二解码电路(101,102)。 当检测到左邻居信息或右邻域信息的传送时,第一和第二解码电路(101,102)中的每一个解码位于区域边缘的解码目标宏块。 区域之间的边界线与对应于彼此相邻的宏块顺序解码的顺序的解码方向正交。

    • A decoding apparatus (100) according to the present invention includes: a decoding unit (101) which decodes identification information identifying an orthogonal transform basis for inverse orthogonal transform; an orthogonal transform basis accumulation unit (110) accumulating orthogonal transform bases for inverse orthogonal transform; an orthogonal transform basis storage unit (103) storing an orthogonal transform basis for inverse transform, from among the stored orthogonal transform bases; an inverse orthogonal transform unit (112) which performs inverse orthogonal transform using the identified orthogonal transform basis; and an orthogonal transform basis transfer control unit (102) which transfers the identified orthogonal transfer basis from the orthogonal transform basis accumulation unit (110) to the orthogonal transfer basis storage unit (103) only when the identified orthogonal transform basis is not yet stored therein. With this structure, it is possible to reduce the memory bandwidth for the memory storing the orthogonal transform basis and the memory access latency.
